Short true crime book about a Napa murder in 1974. Very interesting and something I'd never heard of. Really makes one grateful for new technologies and detectives who never give up.

 However, I will say and I've always heard that when a case starts going cold then the victim's family just needs to keep pressing the detectives for information, leads, and what's going on. They will be more apt to keep it open if they keep hearing from you. Just like in this case...the sister never gave up so the police didn't either.
